Bridge driver today has no support to forward the userspace timestamp packets and ends up resetting the timestamp. ETF qdisc checks the packet coming from userspace and encounters to be 0 thereby dropping time sensitive packets. These changes will allow userspace timestamps packets to be forwarded from the bridge to NIC drivers. Setting the same bit (mono_delivery_time) to avoid dropping of userspace tstamp packets in the forwarding path. Existing functionality of mono_delivery_time remains unaltered here, instead just extended with userspace tstamp support for bridge forwarding path. Signed-off-by:

Eric Dumazet says: ==================== net: gro: cleanups and fast path refinement Current GRO stack has a 'fast path' for a subset of drivers, users of napi_frags_skb(). With TCP zerocopy/direct uses, header split at receive is becoming more important, and GRO fast path is disabled. This series makes GRO (a bit) more efficient for almost all use cases. ==================== Link: https://lore.kernel.org/r/20240301193740.3436871-1-edumazet@google.comSigned-off-by:

In tcp_gro_complete() : Moving the skb->inner_transport_header setting allows the compiler to reuse the previously loaded value of skb->transport_header. Caching skb_shinfo() avoids duplications as well. In tcp4_gro_complete(), doing a single change on skb_shinfo(skb)->gso_type also generates better code. Signed-off-by:

Currently the so-called GRO fast path is only enabled for napi_frags_skb() callers. After the prior patch, we no longer have to clear frag0 whenever we pulled bytes to skb->head. We therefore can initialize frag0 to skb->data so that GRO fast path can be used in the following additional cases: - Drivers using header split (populating skb->data with headers, and having payload in one or more page fragments). - Drivers not using any page frag (entire packet is in skb->data) Add a likely() in skb_gro_may_pull() to help the compiler to generate better code if possible.

Change skb_gro_network_header() to accept a const sk_buff and to no longer check if frag0 is NULL or not. This allows to remove skb_gro_frag0_invalidate() which is seen in profiles when header-split is enabled. sk_buff parameter is constified for skb_gro_header_fast(), inet_gro_compute_pseudo() and ip6_gro_compute_pseudo().

skb_gro_header_hard() is renamed to skb_gro_may_pull() to match the convention used by common helpers like pskb_may_pull(). This means the condition is inverted: if (skb_gro_header_hard(skb, hlen)) slow_path(); becomes: if (!skb_gro_may_pull(skb, hlen)) slow_path(); Signed-off-by:

port_enable and port_disable clears the link settings. Move that to mt7530_setup() and mt7531_setup_common() which set up the switches. This way, the link settings are cleared on all ports at setup, and then only once with phylink_mac_link_down() when a link goes down. Enable force mode at setup to apply the force part of the link settings. This ensures that disabled ports will have their link down. Suggested-by:

There is no need for a separate function to call priv->info->mac_port_config(). Call it from mt753x_phylink_mac_config() instead and remove mt753x_mac_config(). Signed-off-by:

Arınç ÜNAL authored
priv->info->cpu_port_config() is used for MT7531 and the switch on the MT7988 SoC. It sets up the ports described as a CPU port earlier than the phylink code path would do. This function is useless as: - Configuring the MACs can be done from the phylink_mac_config code path instead. - All the link configuration it does on the CPU ports are later undone with the port_enable, phylink_mac_config, and then phylink_mac_link_up code path [1]. priv->p5_interface and priv->p6_interface were being used to prevent configuring the MACs from the phylink_mac_config code path. Remove them now that they hold no purpose. Remove priv->info->cpu_port_config(). On mt753x_phylink_mac_config, switch to if statements to simplify the code. Remove the overwriting of the speed and duplex interfaces for certain interface modes. Phylink already provides the speed and duplex variables with proper values. Phylink already sets the max speed of TRGMII to SPEED_1000. Add SPEED_2500 for PHY_INTERFACE_MODE_2500BASEX to where the speed and EEE bits are set instead. On the switch on the MT7988 SoC, PHY_INTERFACE_MODE_INTERNAL is being used to describe the interface mode of the 10G MAC, which is of port 6. On mt7988_cpu_port_config() PMCR_FORCE_SPEED_1000 was set via the PMCR_CPU_PORT_SETTING() mask. Add SPEED_10000 case to where the speed bits are set to cover this. No need to add it to where the EEE bits are set as the "MT7988A Wi-Fi 7 Generation Router Platform: Datasheet (Open Version) v0.1" document shows that these bits don't exist on the MT7530_PMCR_P(6) register. Remove the definition of PMCR_CPU_PORT_SETTING() now that it holds no purpose. Change mt753x_cpu_port_enable() to void now that there're no error cases left.

Remove error returns on the cases where they are already handled with the function the mac_port_get_caps member in mt753x_table points to. mt7531_mac_config() is also called from mt7531_cpu_port_config() outside of phylink but the port and interface modes are already handled there. Change the functions and the mac_port_config function pointer to void now that there're no error returns anymore. Remove mt753x_is_mac_port() that used to help the said error returns. On mt7531_mac_config(), switch to if statements to simplify the code. Remove internal phy cases from mt753x_phylink_mac_config(), there is no need to check the interface mode as that's already handled with the function the mac_port_get_caps member in mt753x_table points to.

For the switch on the MT7988 SoC, the mac_port_config member for ID_MT7988 in mt753x_table is not needed as the interfaces of all MACs are already handled on mt7988_mac_port_get_caps(). Therefore, remove the mac_port_config member from ID_MT7988 in mt753x_table. Before calling priv->info->mac_port_config(), if there's no mac_port_config member in mt753x_table, exit mt753x_mac_config() successfully. Remove calling priv->info->mac_port_config() from the sanity check as the sanity check requires a pointer to a mac_port_config function to be non-NULL. This will fail for MT7988 as mac_port_config won't be a member of its info table. Co-developed-by:

Yunsheng Lin says: ==================== remove page frag implementation in vhost_net Currently there are three implementations for page frag: 1. mm/page_alloc.c: net stack seems to be using it in the rx part with 'struct page_frag_cache' and the main API being page_frag_alloc_align(). 2. net/core/sock.c: net stack seems to be using it in the tx part with 'struct page_frag' and the main API being skb_page_frag_refill(). 3. drivers/vhost/net.c: vhost seems to be using it to build xdp frame, and it's implementation seems to be a mix of the above two. This patchset tries to unfiy the page frag implementation a little bit by unifying gfp bit for order 3 page allocation and replacing page frag implementation in vhost.c with the one in page_alloc.c. After this patchset, we are not only able to unify the page frag implementation a little, but also able to have about 0.5% performance boost testing by using the vhost_net_test introduced in the last patch.

The page frag in vhost_net_page_frag_refill() uses the 'struct page_frag' from skb_page_frag_refill(), but it's implementation is similar to page_frag_alloc_align() now.

Currently there seems to be three page frag implementations which all try to allocate order 3 page, if that fails, it then fail back to allocate order 0 page, and each of them all allow order 3 page allocation to fail under certain condition by using specific gfp bits. The gfp bits for order 3 page allocation are different between different implementation, __GFP_NOMEMALLOC is or'd to forbid access to emergency reserves memory for __page_frag_cache_refill(), but it is not or'd in other implementions, __GFP_DIRECT_RECLAIM is masked off to avoid direct reclaim in vhost_net_page_frag_refill(), but it is not masked off in __page_frag_cache_refill(). This patch unifies the gfp bits used between different implementions by or'ing __GFP_NOMEMALLOC and masking off __GFP_DIRECT_RECLAIM for order 3 page allocation to avoid possible pressure for mm. Leave the gfp unifying for page frag implementation in sock.c for now as suggested by Paolo Abeni. Signed-off-by:

napi_alloc_frag_align() and netdev_alloc_frag_align() accept align as an argument, and they are thin wrappers around the __napi_alloc_frag_align() and __netdev_alloc_frag_align() APIs doing the alignment checking and align mask conversion, in order to call page_frag_alloc_align() directly. The intention here is to keep the alignment checking and the alignmask conversion in in-line wrapper to avoid those kind of operations during execution time since it can usually be handled during compile time. We are going to use page_frag_alloc_align() in vhost_net.c, it need the same kind of alignment checking and alignmask conversion, so split up page_frag_alloc_align into an inline wrapper doing the above operation, and add __page_frag_alloc_align() which is passed with the align mask the original function expected as suggested by Alexander.

Stephen Rothwell and kernel test robot reported that some arches (parisc, hexagon) and/or compilers would not like blamed commit. Lets make sure tcp_sock_write_rx group does not start with a hole. While we are at it, correct tcp_sock_write_tx CACHELINE_ASSERT_GROUP_SIZE() since after the blamed commit, we went to 105 bytes. Fixes: 99123622 ("tcp: remove some holes in struct tcp_sock") Reported-by:

Add the dependsOn test check for all the mirred blockcast tests. It will prevent the issue reported by LKFT which happens when an older iproute2 is used to run the current tdc. Tests are skipped if the dependsOn check fails. Reported-by:

Matthieu Baerts says: ==================== mptcp: userspace pm: 'dump addrs' and 'get addr' This series from Geliang adds two new Netlink commands to the userspace PM: - one to dump all addresses of a specific MPTCP connection: - feature added in patches 3 to 5 - test added in patches 7, 8 and 10 - and one to get a specific address for an MPTCP connection: - feature added in patches 11 to 13 - test added in patches 14 and 15 These new Netlink commands can be useful if an MPTCP daemon lost track of the different connections, e.g. after having been restarted. The other patches are some clean-ups and small improvements added while working on the new features. ==================== Signed-off-by:Matthieu Baerts (NGI0) <matttbe@kernel.org>

This patch adds a new helper userspace_pm_get_addr() in mptcp_join.sh. In it, parse the token value from the output of 'pm_nl_ctl events', then pass it to pm_nl_ctl get_addr command. Use this helper in userspace pm dump tests. Signed-off-by:

The command get_addr() of pm_nl_ctl can be used like this in in-kernel PM: pm_nl_ctl get $id This patch adds token argument for it to support userspace PM: pm_nl_ctl get $id token $token If 'token $token' is passed to get_addr(), copy it into the kernel netlink. Signed-off-by:

This patch renames mptcp_pm_nl_get_addr_doit() as a dedicated in-kernel netlink PM get addr function mptcp_pm_nl_get_addr(). and invoke a new wrapper mptcp_pm_get_addr() in mptcp_pm_nl_get_addr_doit. If a token is gotten in the wrapper, that means a userspace PM is used. So invoke mptcp_userspace_pm_get_addr() to get addr in userspace PM list. Otherwise, invoke mptcp_pm_nl_get_addr().

This patch implements mptcp_userspace_pm_get_addr() to get an address from userspace pm address list according the given 'token' and 'id'. Use nla_get_u32() to get the u32 value of 'token', then pass it to mptcp_token_get_sock() to get the msk. Pass 'msk' and 'id' to the helper mptcp_userspace_pm_lookup_addr_by_id() to get the address entry. Put this entry to userspace using mptcp_pm_nl_put_entry_info(). Signed-off-by:

This patch adds a new helper userspace_pm_dump() to dump addresses for the userspace PM. Use this helper to check whether an ID 0 subflow is listed in the output of dump command after creating an ID 0 subflow in "userspace pm create id 0 subflow" test. Dump userspace PM addresses list in "userspace pm add & remove address" test and in "userspace pm create destroy subflow" test. Signed-off-by:
